Have you ever seen the difference between a still pond that turns green and smelly, and a clear stream running over the rocks? Water that sits still rots. Water that runs is fresh and good to drink!
The Bible says our words are like that. When we just complain or talk about the bad things other people do, it's like a puddle of mud. But when we speak words of kindness, encouragement, and truth, it's like a fresh stream that does good to whoever hears it! Jesus said He gives us living water inside, and when that living water lives in our heart, the words that come out of our mouth start to taste like life too!
